Hello, I noticed there aren't many reviews of the NFB28 on Head-Fi, and as a big fan of the unit, I felt that it deserves more praise. I will preface in saying that this is the first balanced DAC and amp that I have owned, and the unit was purchased second hand from another Head-Fi member. Kingwa was gracious and allows for warranty transfers, so big shoutout for that!     Build Quality: The NFB28 makes a pretty big first impression with the size and weight alone. It's far more hefty than my previous amps and DACs, with a solid aluminum chassis...
